As prepared photocatalytic materials were characterized by powder X-ray diffraction (XRD), Scanning Electron Microcopy (SEM), Fourier Transform Infrared spectroscopy (FTIR), Positrons Annihilation Lifetime Spectroscopy (PALS) and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) to assess their physicochemical properties. Their photocatalytic decomposition and disinfection activity of bacteria in municipal sewage water was studied. The XRD studies reveal the presence of TiO in the form of anatase phase in the supported composite. The XRD studies further suggested that well crystalline form of TiO onto calcium alumino silicate beads (CASB) supports. FTIR results revealed the presence of Ti-O-Si linkages in the TiO/CASB composite, which are responsible for its higher photocatalytic activity in the destruction of bacterial mass in the sewage water. TiO deposited CASB composite showed drastic reduction in the colony forming unit (CFU) of sewage water with UV light. Copyright@ International Science Community Association
